Application filed October 28,]885. Serial No. 181,150.

(No model.)

To @ZZ whom, t may concern:

Be it known that I, JOHN C. NULL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have-invented a certain new and useful Improvement in Anti-Rattlers for Thill-Coup linge; and I do hereby declare that the follow-` ing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to mane and use the saine, reference being had to the accompanying' drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to improvements in auti-rattlers for thill-couplings; and it consists of aiiat piece of steel suitably bent'and inserted between the thill-iron and the jack-clip, as will be fully hereinafter set forth.

The object is to so form an anti-rattler that it will be secure Within its bearings. I attain the object by the mechanism illustrated in the accompanying drawings, in' which- Figure lisa side view cfa thill-coupling with the antl-rattler in position. Fig. II is a side View of the auti'rattler.

C is the thill-iron, and Athejackclip, which are connected by the usual form of bolt.

B, Fig. I, shows the anti-rattler in position between the thill-iron and the front surface of the jack-clip. The front bearing-surface is circular, and rests against the thill-iron. The back is curved and bears against the jack-clip, and a projectionlof the back at the top extends over a shoulder of the said clip.

At B, Fig. Il, is shown the form ofthe antirattler before its insertion,Whichslightlycoms presses the same. The steel plate is bent upon itself, the front having the two curves s and u, at the junction of which a prominence is 4o l and placed between the thill-iron and the jack- 5o clip to serve as an lulti-rattler, and I therefore claim only the specific form herein set forth.

Having fully described myinventiomwhat I claim, and desire to secure b`y Letters Patent, is- 55 An anti-rattler for thill-couplings formed of steel plate of uniform width bent upon itself, with double curves on its front face and a backward curve or projection at the top, and g from this point a forward projection, substan- 6o tially as shown and described. v

In testimony that I claim the foregoing as my own I ax my-si gnature in presence of two witnesses.
